Title: Improvements in or relating to apparatus for pickling metal tubes
IPC: F02M7/26
Filed: 1938-04-01
Abstract: 495,685. Pickling metal tubes. LATTRE, P. DE. April 1, 1938, No. 10012. Convention date, April 10, 1937. [Class 82 (ii)] In apparatus for pickling metal tubes, in which a batch of tubes is lowered into and lifted from the bath by two coacting hoisting devices, these devices are so operated that the batch is brought to rest in an inclined position at the end of each upward and each downward stroke, the direction of inclination being reversed at each cycle so that the solution drains alternately from each end of the tubes. In the apparatus shown, two batches of tubes 5, 5<1> are suspended from rocking members 4, supported at their ends in forks 3, 31 which are raised and lowered by pivoted beams 1, 11 rocked by connecting-rods 7, 7<1> operated from rotating crank arms 8, 8<1>. The crank arms 8, 8<1> are off-set in relation to one another, so that the up and down movements of the ends of each member 4 are out of phase, with the result that the batches of tubes are raised from and lowered into the bath whilst inclined, and their direction of inclination is reversed both when they are immersed and when they are raised above the bath. In both these positions the driving mechanism is stopped for a period by a time switch, to give the solution time completely to fill and drain from the tubes. In modifications, the members supporting the tubes are carried at the ends by verticallymoving plungers operated in out-of-phase relation by cranks, or by racks engaging pinions driven by motors which are reversed by switch contacts carried by the plungers and engaging spaced fixed contacts. In a further modification, the ends of the tube-supporting members 4 are carried by nuts which traverse up and down rotating screwed shafts.

Title: Improvements in or relating to emulsions of bitumen, resins, waxes or the like
IPC: C08L95/00
Filed: 1935-04-01
Abstract: Aqueous emulsions of natural or artificial bitumen, asphalt, petroleum pitch, resins, or waxes made with clay as an emulsifying-agent comprise a major proportion of one or more of the above materials having a relatively high melting or softening point and a minor proportion of one or more of the above materials of relatively low melting or softening point, the components being emulsified as separate constituents, and not fused together. The lower melting or softening material is preferably solid or semi-solid, but adhesive, at the temperature of use, preferably melting or softening about 10 DEG  C. above such temperature, and acting as a matrix to cement together the harder particles.  The emulsion may also contain dispersed unmeltable materials such as filling or fibrous materials or colouring matters such as iron oxide red, or chromium oxide green.  The final emulsion may be p  prepared by mixing separate emulsions of the constituents, or one constituent may be emulsified and a further constituent emulsified in the emulsion so produced.  According to examples: (1) emulsions containing 50 per cent of water were prepared with the aid of clay from petroleum asphalts having softening points according to K.S. of 30 DEG  C., 40 DEG  C., and 90 DEG  C., and from natural asphalt having a softening point of 130 DEG  C.  The final emulsion was prepared by mixing 20 parts: 10 parts: 30 parts: and 40 parts of the above emulsions respectively.  (2) 72 parts of an emulsion consisting of 45 parts of coal tar pitch with a softening point of 90 DEG  C. according to K.S., 5 parts of clay and 50 pts. of water are added to 28 pts. of red iron oxide.  To 3 pts. of this mixture is added 1 pt. of an emulsion containing 55 pts. petroleum asphalt having a softening point of 35 DEG  C., 5 pts. clay and 40 pts. water. The pasty emulsion produces a coherent film which is not too soft in strong sunlight.  (3) An emulsion is prepared from 50 pts. Gilsonite-asphalt (softening point 120 DEG  C.) 5 pts. clay and 45 pts. water.  45 pts. of soft cumaron resin (softening point 30 DEG C.) are emulsified with 6 pts. clay and 49 pts. of water.  80 pts. of the first emulsion were stirred with 20 pts. of the latter emulsion. The products may be used as paints, protective coatings, cements, &c. Specifications 316,780, [Class 81 (i)], and 362,577, are referred to. The Specification as open to inspection under Sect. 91 is not restricted to clay as the emulsifying-agent, but also describes the use of alkalis, fats, fatty oils, fatty acids, resins and their saponification products, sulphite waste liquor, starch-flour, and gelatinous materials.  Examples describing emulsions made with the aid of soap and turkey red oil are included.  This subject-matter does not appear in the Specification as accepted.

Abstract: 306,379. Siemens & Halske Akt.-Ges. Feb. 18, 1928, [Convention date]. Addition to 298,184. Ratchet and like step-by-step conveyers and elevators.-The invention consists in improved means for transferring goods from a conveyer of the kind described in the parent Specification to a successive conveyer or to a part of the same conveyer above another bath. On the apparatus shown in Fig. 1 the goods are suspended from rods 44 supported in notched members 45 on an eccentrically moving frame 43; the rods 44 are carried forward in an arcuate path until lifted from the frame 43 by a second eccentrically moving frame 42 which again carries them forward. The transfer means consists of two pairs of levers 38, 39 pivoted at the ends of a cross-bar 33 on a pillar 32 mounted on a fixed frame 31. The levers are actuated by connecting rods 41, 40 connected to the moving frame 42. The bars 44 are lifted by the leverpair 39, the notched ends of which at the uppermost point of their travel come into alignment with the notched ends of the lever-pair 38 into which the bars 44 are then deposited by gravity and in which they are retained by a locking spring 38<a>. The bars 44 are then lowered on to notched members 45 of the next stage. The pivotal centres of the levers 38, 39 are adjustable in slots 34, 35 and the points of connection of the connecting rods 41, 40 are similarly adjustable. The levers and the connecting rods are of adjustable length. The position of the notched members 45 on the moving frames is also adjustable. At the end of the treatment, the goods are removed from the bars 44 which are' then returned to the starting point by an inclined plane 51, Fig. 3, where they are retained by a stop 54. The bars are lowered by a lever 50 actuated by a connecting rod 55 by the frame 42 on to a bracket 52 from which, after loading the goods they are deposited on the frame 43 by transfer means of the kind already described.

Filed: 1974-03-07
Abstract: 1437694 Dual brake systems GENERAL MOTORS CORP 7 March 1974 [26 March 1973] 10260/74 Heading F2F An hydraulic brake system comprises a tandem master cylinder 10, the chambers 26, 28 of which respectively pressurize separate brake circuits 42, 50, and a piston and cylinder device which cuts off brake fluid supply to one circuit if that circuit fails and includes a one-way valve 116 which allows pressure of the cut-off supply to be connected through a conduit 126 to augment the supply to the other circuit, but, if the other circuit fails, prevents augmentation of pressure fluid to the one circuit. As shown, circuit 50 supplies front wheel brakes 52, 54 and circuit 42 supplies rear wheel brakes 44, 46. If the front brake circuit 50 fails the pressure in a chamber 84, connected by an inlet to master cylinder chamber 28, and by an outlet 98 to the circuit 50, decreases and the pressure acting in a further chamber 86, connected to the other master cylinder chamber 26 causes leftward movement of a shuttle piston 70. An extension 88 of piston 70 having a seal 92 moves into a recess 100 to cut-off fluid supply to the front circuit 50. Fluid pressure is then built up in chamber 84 and passes via conduit 126 and one-way valve 116 to augment the fluid pressure in the circuit 42. If the latter circuit fails shuttle piston 70 moves rightwardly a further extension 90 engaging sealingly in a passage 110 to close off communication with conduit 126, and hold valve 116 closed. A land 76 of the piston 70 severely restricts fluid flow through outlet 108 to rear wheel brake circuit 42. No communication is thereby possible to augment the fluid supply to circuit 50.
